A, the conduction oil in transformer store oil main body flows into each grease chamber from the mozzle of upper end；
B, the conduction oil in grease chamber is flowed into heat sink, and the strip bulge of heat sink inner cavity surface fully contacts with conduction oil,
And increase heat-conducting area；
C, the outer surface of heat sink is arranged in corrugated strip bulge and the heat of conduction oil is transmitted into the external world, while ripple
The radiating fin increase of shape wave and the contact area of air, improve radiating effect；
D, air in side package plate and the air-vent of single chip package plate bottom by flowing into, because air heats can rise,
The top of side package plate and single chip package plate is closing, will form pressure difference, form larger convection current, accelerate air
The speed of flowing, meanwhile, when air flows through corrugated strip bulge and radiating fin, it can be filled by certain resistance
The heat exchange divided, improves heat dispersion；
E, last, conduction oil flows back to transformer store oil main body from the mozzle of lower end.
Compared with prior art, the invention has the advantages that：
The strip bulge of the inner cavity surface of heat sink of the present invention is arranged in order the contact surface of waviness, inner cavity surface and conduction oil
Increased twice than original plane, accelerate the speed that inner chamber is outwards conducted heat, meanwhile, the outer surface of heat sink and radiating fin
The area of dissipation of similarly undulate, radiating fin and outer surface equally increases twice, and radiating fin is changed to wave
While shape, the windage that radiating fin radiates up and down is increased, improves heat dissipation；In addition, the both sides increase of radiator element is single
Piece package board, and after multiple radiator elements connect into whole group, the side of whole group radiator element is also closed, and adds side
Portion's package board, after closing, the upper and lower of cooling system will form pressure difference, form superpower convection current from bottom to top, air is by radiating
Hole flows into, and is flowed out by top, has speeded radiating rate significantly, and radiating rate is doubled left and right.
